datasheet for 25SH53 by Micro Oscillator, Inc.

Silicon Oscillators
“SH32” and “SH53” Series
MERCURY
Since 1973
The “SH” series is an extremely low power precision silicon oscillator with a total
frequency error of less than 1.0%. This Si-gate CMOS oscillator produces a
square wave output and requires no external components other than power
supply bypass capacitors. The operating voltage range is from +1.5V to +3.3V,
which allows operation from a single Li-Ion cell or 2 AA alkaline cells.
SH53
Features:
Hermetically sealed& metal-lid grounded ceramic leadless package
Superior moisture resistant, compared to plastic molded packaging
Internally frequency tuned to the specified voltage
(no external components needed)
Ultra-low supply current [10 uA typical at +2.5V]
Fast start up time
+1.55V to +3.3V single supply voltage
Withstands high vibration and harsh environments
Suitable for light weight, compact consumer electronic devices
Ideal for high density boards
RoHS compliant and (Pb) lead-free product
United States Patent No: 6,281,732*

Notes:

1/ Output signal frequency is stable by the second pulse cycle, after the supply voltage is stable. This time
is dependent on the oscillator frequency, and it is given for 32.768 KHz.
2/ Oscillator start up requires a relatively clean supply voltage that does not drop down towards zero volts
during turn on. After the supply voltage drops below about 1v, the voltage should go to 0v for 0.3 sec.
min before the oscillator is turned on again.
